How does a fantech system work?
An HRV transfers “sensible” energy (Heat/Cool) from the high (heat) to the low (cool), tempering the cool air in/out. An ERV transfers the “sensible” energy the same as the HRV, it also transfers “Latent” energy (humidity) from the high (warm) to the low (cool) side.

Should you leave your air exchanger on all the time?

How do I use my HRV in the winter?

What should my HRV be set at in summer?
As a general rule of thumb, you should set your system’s dehumidistat to 25 percent to 50 percent depending on the temperature to keep condensation at bay. For instance, 50 percent is the maximum relative humidity you should have if the outdoor temperature is between -11 degrees Celsius to 18 degrees Celsius.
How much is heat recovery ventilation?
Does heat recovery ventilation cost much to run? The cost to run a heat recovery ventilation system per year depends on the size of the house. The larger the house the more air needs to be moved and so the fans have to work harder. A house of 250m2 would cost in the region of €40 to €60 per year to run.
